JOHN OWENS, OF KINGSTON, IOWA.

GASOLENE-LAMP.

To all whom it may concern:

Be it known that I, JOHN OwENs, a citizen of the United States, and a resident of Kingston, in the county of Des Moines and State of Iowa, have invented a certain new and useful Improvement in Gasolene- Lamps, of which the following is'a specification.

My present invention relates generally to gasolene lamps, and more particularly to the general'construction thereof, as utilized in connection with either gravity feed or force feed gasolene lighting systems.

The primary object of my present improvement is to provide a gasolene lamp, the construction, connection, and cooperative action of the several parts thereof being such as to not only permit ofinstallation of the lamp in the first instance, but the detachment, repair or substitution of any one or more of its several parts in a ready, quick, and convenient manner without the necessity of skilled labor or the use of special tools and implements for this purpose.

As is well known, the gasolene lamps now in use are of a complicated construction such that, when the parts thereof become worn, broken, or disarranged, it is necessary for the user to purchase an entirely new lamp, occasioning unwarranted expense and delay and work, and usually requiring the services of a skilled mechanic for both the removal of the old lamp and the installation of the new one.

lVith my present invention these disadvantages may be overcome and the foregoing objects carried out, as plainly to be seen from the following description of the construction, combination, and operation of its several parts, reference being had to the accompanying drawings which illustrate the invention and form a part of this specification.

In the drawings:

Figure 1 is a side view partly in elevation and partly broken away and in section, illustrating the complete lamp as proposed by my invention;

Fig. 2 is a horizontal section taken therethrough, substantially on line 22 of F ig. 1;

Fig. 3 is a detail perspective view enlarged of the upper portion of the lamp, adjacent the hanger casting; 1

Application filed December 8, 1916. Serial N 0. 135,774.

Fig. 4 is a vertical sectional view through the lower central portion of the lamp;

Fig. 5 1s a similar view taken substantially on line 55 of Fig. 4;

on line 88 of Fig. 7

Referring now to these figures, the lamp as proposed by my invention is suspended from a suitable support by means of a hanger pipe 10, as seen best in Figs. 1 and 3, downwardly through which extends the gasolene branch 11 from the gasolene feed pipe, which as well known, leads from a supply tank either by gravity where the tank is elevated, or by force feed in connection with a low-down tank. 1

The lower end of the hanger pipe 10 is securely fastened to the upper portion of a hanger casting 12 having a lower angular portion 13 to which the upper offset extremities 14 of the lamp frame 15 are secured by a bolt or suitable fastening member 16, the lower end of the gasolene branch 11 being detachably connected by a connecting pipe 17 adjacent the casting 12 to the upper end. of a lamp tube 18 carried by one of the side extensions of the frame 15, in a manner to be presently described.

The frame 15, as seen erably in a single piece, being bent to the form shown from a rod, the intermediate portion 19 of which at the base of the lamp is flattened and one side of which is longitudinally grooved to receive the lamp tube 18 in the groove thereof, so that the latter will at all times be within the sight and reach of the user of the lamp, in order that any leak may be readily and quickly detected and as readily and as quickly repaired, the

in Fig. 1, is prefupper end of such tube being detachable, as

previously described, and the lower end thereof being detachably connected by similar means to the controlling member 20.

flattened portion 19 of the frame serving as a support for a collar 23 from which the radially shaped supporting arms 24 extend in order to receive and effectively support a shade 25 of suitable form, as for instance that shown in Fig. 1.

The feed controlling member 20 is also provided with a vertical bore 26, the lower end of which communicates with the lateral bore 27 to which the lowerend of the tube 18 is connected, through a port 28 controlled by a needle valve 29, the upper portion of the depending stem 30 of which is threaded into the lower portion of the feed member 20, so that the stem maybe turned by its lower key 31 to control the feed of gasolene from the lower end of the tube 18, upwardly through the vertical bore 26, the feed member 21 having a lateral bore projecting in the opposite direction from that of the bore 27, and normally closed by a plug 32-by means of which the feed member may be thor' oughly cleaned when desired.

Thus it will be noted that the bore :26 is out of alinement with the needle valve 29, so that pressure cannot act directly in the length of the latter and thus endanger leakage past its threaded portion within the said feed member.

It is also obvious from the construction of the feed controlling member 20 that this portion of the lamp may be readily detached by releasing the screws 21, for repair or substitution, and that this construction permits of cleaning whenever necessary or desirable.

Upstanding above and at one side of the feed controlling member 20 is a gas feeding member 33 having lower laterally projecting ears 34 connected by screws or like fastening members 35 to the flattened portion 19 of the frame and havinga bore 36, the lower portion of which is threaded for the reception of a threaded stem 37, i the lower end of which projects below the frame portion 19 exteriorly of the member 33, and is provided with a key 38.

. The gas feed member 33 is also provided adjacent its upper end with a laterally opening nipple 39 to which is detachably connected one end of a vaporizing pipe 40, the opposite end of which is similarly connected to the upper end of the feed controlling member 20, as particularly seen in Fig. 4, the outer extremity of the gas feeding member 33 being provided with a conical opening into which a conical spray plug 41 extends,

' this spray plug being held in detachable connection with the upper end of the member 33 by means of a gasket nut 42 and having a minute opening through which the gas is sprayed upwardly into the burner pipe 43, the lower portion 44 of the latter of which telescopes upon the upper end of the member 33.

The burner pipe, of an unthreacled U- the flamepfrom the burner will be prevented from blowing over the spray plug 41.

The burners 46 support incandescent mantles of the inverted U-type, as indicated in dotted lines at 47 in Figs. 4, 5, and 6.

The upper end of the stem 37 within the gas feed member 33 is provided with a 1 needle 48 which, by turning the stem 37 to move the same upwardly, may-be projected into and through the minute openingof the spray plug 41 to clean the same should it become wholly or partially clogged, reverse movement of the stem serving to withdraw the needle to its normal position below the spray plug, and permit free passage of the gas through the plug.

It is obvious from the foregoing that the construction and arrangement of the parts as previously described, permits of freely removing the burner pipe 43 or 43, and the removal of the spray plug 41 for repair or n substitution, by unscrewing the gasket nut 42, although the needle 48 at the other end ofthestem 37, actuated in its movements by manipulation of the lower key 38, will serve to dislodge any undesirable accumulation within the minute opening of the plug and maintain-the latter in cleanly condition. As sometimes happens, however, the accumulation within the opening of the plug is such as to prevent movement of the needle 1 through the same, and even break the needle oif, and in such case removal of the plug and insertion of a new one, which can be readily accomplished by the construction provided by my invention, is greatly to be desired.

It'is to be observed, furthermore, that either the feed controlling member 20 or the gas feed member '33 may be independently removed, the vaporizing pipe being detachable from either or both thereof, so that these parts may be independently renewed or repaired without disturbing the remaining parts.

It is furtherto be observed that the detachable connections of the tube 18 and the vaporizing pipe 40 including a cone at the ends of the pipes held in position within a conical seat in the .connectingmembers,as seen at 49 in Fig. 4 in particular by means of a gasket nut 50, may be modified as to the gasket nut 50 as seen'in Figs. 7 and 8, by the substitution therefor ofa yoke 51, as seen in the latter figures, to engage the cone 49 and force the same into position under pressure exerted by a thumb screw 52 threaded the burner 46, so that through the yoke, thus avoiding the necessi y of threaded engaging parts and the danger of crossing the threads in the hands of unskilled inetlicient operators.

In addition to the foregoing advantages, the construction as proposed by my invention is not only more simple but is considerably cheaper and otherwise more efficient than the constructions heretofore utilized.
